I guess you wanted to ask which header is to be included for string functions. It's string.h
string.h
Not possible through html. Use php strrev function. For eg:
GetA is a math function and not a string function.
The string function is strlength and it is evoked to return the length of a string.
Probably because you haven't include the <string> header anywhere in the translation unit.
Without any function is impossible. So I'll assume you mean any coded function, in which case the predefined function below is your answer.$string = strrev($string);
int find(String str, double d);
string length is a function use to check the lenght of a string i.e number of alphabets in a word or sentence.
between parentheses: funname ("string")

The REPLACE function.
Before a function can be called the compiler needs to know the function's type and the number and type of its arguments to ensure the call is valid. This information is provided by the function declaration, which must be visible to the compiler prior to the point of the call (a forward declaration). With a two-pass compiler, the declaration may be placed before or after the call point. Ideally, function declarations should be placed in a header file, with the functions grouped in some logical manner. For instance, all string-handling functions may be declared in a "string.h" header. in this way, the programmer need only include the header to ensure the declarations are consistent across all translation units that require those declarations. In addition, all types required by the function must also be declared to the compiler. Again, these may be placed in a header to ensure the types are declared consistently.
